Kimberly Kaestner, PMHNP-BC

I'm Kimberly, a psychiatric mental health nurse practitioner dedicated to helping people navigate life’s mental health challenges with compassion, insight, and practical support. I’ve seen how issues like anxiety, depression, trauma, and substance use can take a toll on both emotional and physical wellbeing—and I’m here to help you address those challenges with a thoughtful, collaborative approach to care.

My clinical background includes working in outpatient psychiatry and providing care for individuals facing complex and co-occurring conditions. I’ve worked closely with those navigating substance use recovery, mood instability, trauma-related symptoms, and treatment-resistant depression. These experiences have taught me that mental health care is never one-size-fits-all. Each person’s story is unique, and effective treatment begins with truly listening.

My approach is centered on evidence-based medication management while also incorporating holistic and lifestyle-oriented strategies. I work closely with clients to explore how factors like sleep, nutrition, stress, and social support impact mental health. I believe medication can be a powerful tool, but it’s most effective when combined with long-term coping strategies, therapeutic insight, and individualized wellness planning.

When you work with me, you’re entering a partnership built on trust, mutual respect, and shared decision-making. I take the time to understand your concerns, values, and preferences so we can create a treatment plan that truly fits your life. My clients often say they feel heard, validated, and encouraged in sessions—because that’s my priority. Together, we’ll focus on progress, not perfection, and on creating a life that feels more balanced, meaningful, and manageable.

Whether you’re just beginning your mental health journey or have been managing symptoms for years, my goal is to help you feel supported and empowered every step of the way. I offer a safe, nonjudgmental space to explore your challenges, build insight, and set realistic, meaningful goals for growth. I want you to feel confident that you have a provider you can count on—not just during tough times, but throughout your healing process.
